Apple Ios 9: Increasing Performance

After the original release of iOS 9, several Apple Pickers (Apple users) reported a sudden degradation in performance after upgrading their iOS devices. Users reported issues are commonly in relation to choppy interaction times, lagged responses, screen often gets stuck after rotating the display, and other delayed user interface struggles. I’ve been able to find ways that you can regain performance to your device, but first let’s gain some prospective to why this is occurring and then discuss increasing performance of your device.


More than likely you’ve recently installed iOS 9, after that upgrade there’s several things that occur.

  1. The device must re-index itself. Speed of indexing is fully dependent on how much data is stored on the device, the more you have the longer it will take. Expect this process to take 6-8 hours.
  2. Once the device finishes reindexing, applying its updates. Once it’s updates and app store updates are performed it’s generated a lot of temporary information or “cache”. In order to clear out this unnecessary stored information, you’ll need to do a “force restart” which you’ll learn how to below. This method will also help increase general performance when you’ve gone several weeks without restarting the device.


I know what you’re thinking, “disable one of Siri’s latest and greatest features”. Yes, I’m actually stating that your device is currently better off without this added features, and here’s why. Every time you open spotlight or an application that potentially calls back to it, it’s using device resources and data to pull live information, this could effect your speed drastically.

  • Disable Siri Suggestion – Settings > General > Spotlight Search once here toggle “Siri Suggestions” to off.


Transparency and motions are just a bunch of added eye candy, sure it makes things look slightly cooler, but they really don’t serve any purpose for average Apple Pickers. Disabling these visual effects will decrease the amount of user interface issues as iOS 9 has issues rendering them.

  • Enable Reduce Transparency – Settings > General > Accessibility > Increase Contrast, toggle “Reduce Transparency” on
  • Enable Reduce Motion – Settings > General > Accessibility > Reduce Motion, toggle “Reduce Motion” on


Background App Refresh is a features that enables apps to run in the background of iOS, it’s primary function allows suspended applications to check for new or updated content. The downside of disabling this feature, it will need to pull information upon opening the app instead of the background, either way it still uses the same amount of data.

  • Disable Background App Refresh – Settings > General > Background App Refresh, toggle “Background App Refresh” off


The amount of data being stored on a device can often play a big part in general performance. Ensure that you’ve left at least 15% of your available storage capacity open.

  • Checking Storage Capacity – Settings > General Usage Storage


There’s several different methods of how you should reboot your device and when, I personally have found performing a “forced reboot” is most effective.

  • Hold both the home and sleep buttons at the same time for 10 seconds or until the Apple logo appears.


If these steps still don’t help and your device is unbearably slow it could be one of two things.

  1. You’re using an older device that’s barely allowed to be on iOS 9.
  2. iOS 9 was recently released, sometimes it’s best to wait until a few updates rollout prior to upgrading your device.

This doesn’t really leave you with many options besides either rolling back to iOS 9 or upgrading to newer model of your device.
